Installation procedure on Ubuntu 18.04/20.04

1. Create temporary directory

Example:

mkdir neo

1. Download all *.deb packages

Example:

cd neo
wget https://github.com/intel/compute-runtime/releases/download/21.20.19883/intel-gmmlib_21.1.3_amd64.deb
wget https://github.com/intel/intel-graphics-compiler/releases/download/igc-1.0.7423/intel-igc-core_1.0.7423_amd64.deb
wget https://github.com/intel/intel-graphics-compiler/releases/download/igc-1.0.7423/intel-igc-opencl_1.0.7423_amd64.deb
wget https://github.com/intel/compute-runtime/releases/download/21.20.19883/intel-opencl_21.20.19883_amd64.deb

Quality expectations

All platforms were validated on Ubuntu 20.04 LTS with stock kernel, with the following exceptions:

• Tiger Lake was tested with kernel from drm-tip
  5.8.0-rc7 commit ebef75fc1a3f0abebf46d7270128553f82361bc8 2020-08-02_07-12-33 drm-tip: 2020y-08m-02d-07h-11m-48s UTC integration manifest

Quality levels

• Experimental - no quality expectations
• Early support - platform may not be available on the market yet
• Pre-Release - suitable for integration and testing, gathering customer feedback
• Beta - suitable for integration and broad testing
• Production - Beta + meets API-specific conformance requirements; suitable for production
• Maintenance - Reduced test frequency compared to Production, no longer recommended for new deployments. Reactive support for customers.

Issues & regressions of note

• OpenCL and Level Zero packages provided in this release were compiled with DG1 support disabled
• Unit tests compilation failed with gcc 11, fix in progress
• Regression on Ubuntu 18.04 with kernel from package linux-image-generic. As workaround kernel from package linux-image-generic-hwe-18.04 can be used. Fixed with commit: 21d93a3

Important changes

• Updated IGC
• Updated gmmlib
• Enabled "cl_intel_sharing_format_query" extension
• Enabled Level Zero on ADLS and RKL
